This invention relates to new and useful improb4 nnts in ozone and water mining devices for water-purityingmachines.

In the present state of the art, ozone and water .mixing devices are Vconstructed in a column formation in which means are provided for compelling the liquid to low downwardly from the upper end to the lower end and to iiow ina plurality of vortices so as to produce a partial vacuum at intervals throughout the column. Fur-l tl'iermore, this type ot column is capablel of having itsheightrincreased or diminished to meet the requirements of the conditions at the place of installation. Thus, it a single unit` is-.employed, an extremely high column may becomenecessary if' the requireinents at the place of installation are beyond the 'capacity ot the normal sized unit. This increase in height is due to the necessity of properly mixing the ozone and water when a larger quantity of water is to be purilied. It has been the practice to connect in series a plurality of these mix-v ingcolumns'` to a common inlet pipe. This arrangement, however, is not entirely-satisfactory as it tends to vary the pressure of the water dashing through different units.

Another object oif the invention is to provide an ozone and water mixing unit in which a'circuitous path ot relatively narrow cross cectionalrarea Ais provided whereby the ozone and water will be better mixed owing to the long path'o'f travel and also on ac mit of the narrow passages preventing the ation of large bubbles Y A 'further object of the invention is to provide an ozone and air mixing unit which is constructed or" a plurality of circular bai fie olates which cooperate to form a circui tous path for directing the ozone and water in a radial direction from the center towards the periphery, thus producing a passage having a lengthmuch longer than the height of the unit.

Suitably mounted on a support 5 is ra pluralityot ozone and water mixing units, eachibeing ile gnated as a whole by the reference nin moral ,6. The water supply pipe ./i is connected to a water intake manifold 7 and connected to this manifold isV a plurality 'of water pipes 8 which respectively'cow neet .vith ejeotors 9, there being one ejector connected with the upper portion ot each mixing unit 6.V An ozone intake manifold 10 isconnected by a supply pipe 1()a with the ozone generator B and each ejector 9 is connected to the ozone intake manifold 10 by a pipe 11. rfhe ozone and water mixing unit-s 6 are preferably arranged in a circular series so as to occupy but very little space and so aste be advantageously positioned relative'to the water inlet mani fold 7 and ozone inlet manifold 10% which are centrally disposed above said mining Units.. Q

Each mixing unit (i comprisesl an upper cap 1Q and a lower Icap13 said caps be- The upper cap 12 is formed with a centrally disposed opening 14 and with downwardly en-y tending inner and outer concentric ribs 15 and 165. the inner rib 15 being internally threaded and the lower edge of the rib 1G is formed with a groove 17. It will be understood, of course, that the ribs 15 and 1 6 are circular in outline. The ribs 15 and 16 are disposed in spaced relation, and arranged between these ribs and termed in- 'tion by the nut 24 and packing 25.

tegral with the cap 12, is a plurality of bosses 13, each boss having a groove 19 formed in its lower face. The lower cap 13 is provided on its upper'face with a plurality of curved ribs 2O and 21, which are respectively arranged in alinement with the rib 16 and the bosses 13. The ribs 20 `and 21 are concentrically `arranged and are disposed lin spaced relation. An inner rib 22 projects upwardly from the bottom cap 13 and is disposed in concentric relation.

Disposed within the opening 111 of the upper cap 12 is an inlet pipe 23 for the water and ozone which is to be mixed as it passes through the unit. This pipe terminates at its lower end in spaced relation to but in close proximity to the bottom cap 13. ylhis pipe is capable of being adjusted lengthwise and is held in any adjusted posi- A pipe 26 which is slightly .larger in diameter than the pipe 23 has its lower end threaded onto the upwardly extending flange 22 of the bottom cap 13. The pipe 26 terminates at its upper end in spaced relation to the upper cap 12. The space between the pipes 23 and 26 is vrelatively narrow and forms a passage 27 for the mixture. A third pipe 23 has its upper end threaded and engaged with the threaded rib 15 on the upper cap 12. The lower end of thepipe y23 terminates in spaced relation to but in close proximity to thel lower cap 13. The pipe 23 is of a diameter slightly larger than the intermediate pipe 26 and consequently a narrow passage 29 is formed for the mixture.

Disposed around the pipes and between the upper and lowercaps is a plurality of stacked casing members on castings, each casting being indicated as a whole by the numeral 30. Each casting comprises a spaced pair of inner and outer circular walls 31 and 32 of tapering cross section and forming a circular passage 33 therebetween. The walls 31 and 32 are connected at their lower ends by a circular web 34; which is provided with a yplurality of vopenings Extending inwardly from the lower end of the inner wall 31 isan integral flange 36 which is formed with a plurality of openings 37. rlhe bottom of the wall 31 is formed with afrecess 33 and the bottom of the wall 32 is formed with a recess 39. These castings are stacked one upon the other, the upper ends of the walls 31 and 32 fitting into the recesses 33 and 39, said `recesses being preferably lled with a plastic so as to seal the connections, The lower casting is seated'on the ribs 20 and 21 of the lower cap 13. The upper edge of the outer wall of the upper casting is seated in the recess of the rib 16 whereas the upper edge of the inner wall of the upper casting cooperates with the recesses 19 of thebosses 13.

The several parts are held in fixed relation 'lar wall or baffleV plate. by the spaces 33 of the several castings is by means of a plurality of bolts 40 which engage the upper and lower caps 12 and 13.

The inner walls 31 of the casing members or castings conjointly form a circular wall or baffle plate which is disposed in spaced relation to the pipel 23 so as to form an upwardly Haring or diverging passage 41 for the mixture. Inasm-uch as the bosses 13 are short in length, the passage 41 has direct communication with the passage formed by the spaces 33 between the walls 31 and 32 of 'each casting. It will be observed that the outer walls 32 also conjointly form a circu- The .passage formed indicated by the numeral 42.

It will also be observed that these circular passages are relativelynarrow in'cross section `and as a result of this long and continuous passage, which 'longer than the height of the unit, the ozone and water will be properly mixed. The mixture passes from the unit through a plurality of openings i3 formed in the lower cap 13 and communicating with lthe outermost or peripheral passage Z12.

The mixing units 6 lare supported on the top of a discharge tank 415 and this tank is 'formed with a conical lower portion 16 which terminates at its lower end in an outi let opening 17 having a' valve 43 connected therewith. Asa result of this conical bottom 455, the mixture will, providing the valve 113 is open, 'flow outwardly unrestricted inasmuch as a vortext will be formed by the conical bottom portion 46, and any surplus ozone which may. be in the tank will be spotted outwardly through the outlet pipe i From the foregoing, -it will be seen that the height of each unit vmay be adjusted to suit requirements by yadding to or taking away one or more of the castings 30. `When such -an adjustment is being made, the end cap 12 may be readily shifted and at the same timethe pipes 23, 26 and 23, which are disposed in telescopic relation will be relatively shift'ed endwise.

'/Vhen assembling a unit, the pipe 26 is screwed onto the rib 22 ofthelower cap 13, and the pipe 23 is screwed'onto the rib 15 of the upper cap 12. rEhe cast-ings 30 are then positioned -in superposed reiation on the ribs 20 and l21 of lthe lower cap 13, the

joints between the castings being sealed by a suitable plastic. Theupper cap -12 with the pipe 23 attached Athereto is vthen placed on the top ofthe castings, the upper edge of the outer wall of the -top castingfitting into the recess 17 of the rib 16 which is carried by the upper cap. rEhe vbosses 13 of the upper cap serveto steady the castings. The pipe 23 is of coursepositioned-between the castings and the pipe 26. The bolts 210 are then utilized to clamp the upper and is several times f"" lower caps awainst the superposed castings. The inlet pipe 23 is 'then positioned in the opening 24 and is rigidly secured therein by the nut 24 and packing 25, the correspond ing ejector 9 being connected to the upper end or the inlet pipe 23.

In operation, water is ted under pressure through the pipe A to the water intale manifold 7 and from this manifold the water is evenly distributed to the ejectors and thence to the inlet pipes 2B ot the mixing units. rlhe .ozone is ted from the generator B through the pipe 10L to the ozone intake manifold l0. yEhe water passing through the ejectors draws equal quantities olf ozone from the ozone manifold 10 through the pipes l1 to the respective ejectors rlie water and ozone thus begin to mix in the ejectors. The water and ozone are thence ted under pressure through the inlet pipes 23 to the Aseveral mixing units. The mixture then passes upwardly through the passage 2T formed by the pipes 23 and 26, thence over the upper end ot the `pipe. 26 and down the passage 29 formed by the pipes 26 and 28. The mixture then passes upwardly through the passage 4l formed by the pipe 28 and the inner and upwardly tapering walls of the castings, thence over the top of the uppermost inner wall and thence downwardly through a passage 42 formed by the converging aligned spaces 33 ot the castings. The water and ozone are thus thoroughly mixed, and the mixture then passes outwardly through the openings 43 which are formed .in the lower cap. The mixture then passes into the discharge tank 45 and as the mir:- ture strikes the lower or conical portion of the tank, the valve 48 being open, a. vortex is produced which draws any surplus ozone, which might be in the tank, into the pipe line and distributes it into a swimming pool or other place.

Also by reason of the tapering cross section of the circular units which form the built-up circular walls 3l and 32, a. plurality of upwardly diverging and downwardly converging chambers are formed within adjacent concentric rings, The effect of this construction is to further agitate the passag of the water and ozone through the appara tus, thereby to insure thorough mixing.

From the Aabove it will be seen that in Yeach mixing unit, there is an extremely narrow circuitous passage for the water and ozone and by reason of the vertically dis posed baffles, the water is turned over several times during` its complete passagethrough the unit. The' possibility of creating large bubbles is thereby avoided, and the water and ozone are compelled to mix so as to render the water sterile.
